What is the shelf life of various test chemicals?
How should I dispose of any unused chemicals?
-Thanks

good test kits have expiration dates, on all their chemicals. more inexpensive ones usually last for a year or two depending on manufacturer and the chemicals themselves. you can e-mail your test kits manufacturer to get life expectancy of the kits from them.
disposal should done in accordance with your local codes. it varies from place to place.

IMVO, Leading brands of test kits are good for years, even after they expired... The only reason why makers inprint an expiration date on the box is so that they aren't liable for discrepancies or innacuracy due to age of test kit. in other words they are not as reliable as newly purchased kits.. and theres no guarantees what so ever...
Consumers usually tend to buy new test kits when the expiration date arrives..regarless of product's left overs .
I still use a few test kits that i got about a decade ago. (salifer of course). they're still reliable, accurate and rookie-proof. how do i know?? well, i double check and confirm results with the lfs's..
Chemicals/supplements in the dry form will last almost untill u ran out of them..
Liquified forms will only be good for a couple years or upon expiration date stated..

Usually, by the time they have expired; you'll have enough experience to just "sense" that the kit isnt reading properly. I agree with Aztec Reef above and use them well beyond expiration date. As to disposal; I would think that if they don't have any hazardous warning labels (I've neve seen one), they could just go out with the garbage. Used test water sure needs no special handling.

Usually peeps that know how to spell zoothanthellae, have a sense when water chemistry is out of whack.. And thats when those people do elaborate testings.. But if tank has been stable and mature and no alterations to water chemistry have been made in a while.. theres no reason for everyday or even every week testing..
Also i take water samples whenever i visit the lfs, just to have that little peace of mind,, and if lfs's test results dont convince me, i just play along...
until farther analises which results in debunking the lfs theories.
I rarely do testings, Im getting so good at detecting impurities in water column that all i have to do is taste it..soon i wont be surprised if i mutate into a fish..
Thus the reason why some of my test kits are past way beyond expiration date...However i always have every test kit available, just for kicks. Or in case i feel like doing some contraversial experiments which enables me to give the lfs a taste of their own medecine
(harassment). with a poquito of missinformation..

This is very common; nitrates at this level won't hurt fish; a big misconception, IMO. Inverts are another story.

True, but too bad that same water that fishes swin in is also plumed to the other holding tanks that house inverts and sometimes corals..(except that fancy show tank that they keep by the lfs's entrance).. Lets not forget that they also like keeping salt levels @ mucho low.

Yeah. I remember, before LR & inverts, many experienced hobbiests kept fish only at around 1.017.
